Ordinary Portland cement often causes slow strength development and construction delays. Rapid-hardening cement offers faster construction, cost-effectiveness, reduced maintenance, and improved durability, making it ideal for emergency repairs, cold weather concreting, and precast concrete production. Rapid-hardening concrete is a specialized type of concrete that gains strength at an accelerated rate, allowing for faster construction and reduce project timelines. This study focuses on the use of Table Salt (NaCl), Bama gravel, river sand, and crushed stone to produce rapid-hardening concrete. Concrete mix design was evaluated using Microsoft Excel spreadsheet (MATLAB Application) based on BS 8500 Mix Design Method. The standard cubes of 150mm × 150mm × 150mm, were produced for compressive strength tests. A total of 60 cubes were cast using mix proportions of 1:0.63:0.09:0.95:0.36 (cement: river sand: Bama gravel: crushed stone: water). The materials were mixed with up to 4% NaCl in an increment rate of 1% as a partial replacement of cement. The aggregate qualification tests revealed that the materials used are within the stipulated codes and standards. The hydration properties results showed that the percentage replacement of NaCl increases the consistency, reduces setting times, and increases early strength gain. The mix proportion adequately produced rapid-hardening concrete with a compressive strength of 33.23 N/mm2 in 1 day. However, there is a deviation of 3.83% in the target strength, though concrete with high-performance properties of 57.67 N/mm2 at 4% NaCl replacement was achieved at 28 days. Rapid-hardening concrete should be used in the construction in cold-weather, hydraulic structures like bridges, culverts, dams, drainages, and highway pavements due to rapid settings and early strength gain characteristics.

Exclusive Breastfeeding in the first six months of life is recognized as indispensable component of survival, physical and mental development of children. Despite the enormous benefits of Exclusive Breastfeeding only 39%of infants less than six months of age are exclusively breastfed globally .This study aims to assess the Nutritional status of infants, aged 0-6 Months (Exclusively breastfed and non-exclusively breastfed) was conducted at BOWEN University Teaching Hospital and Ibrahim Taiwo Primary Health Care Center, Oyo State, Nigeria.<br> The study is a cross sectional comparative study carried out with the aid of questionnaires and anthropometric measurements of infants to compare the nutritional status of Infants that are exclusively breastfed and non-exclusively breastfed. The participants were recruited by simple random sampling. Data was analysed using SPSS. Majority of the participants were in the age range of 21-30 years. Their main source of information on breastfeeding was from healthcare professionals. Most of the participants breastfed their babies but not all of the mothers practiced exclusive breastfeeding.82.66%mothers practiced EBF at PHC and 24.62% practiced EBF at BUTH.86.6%intiated breastfeeding immediately after birth at PHC and 53.85%intiated breastfeeding immediately after birth at BUTH. The result also shows that there is association between exclusive breastfeeding and nutritional status of infants.<br> Findings from this study shows that most of the participants have good knowledge of exclusive breastfeeding and more advocacy and education must be intensified to achieve WHO recommended target if 90% nursing mothers practice EBF.

ABSTRACT<br> This study investigated the impact of dietary lemon grass (Cymbopogon citratus) on the intestinal morphology of weaner rabbits. A total of sixty rabbits were randomly assigned to five dietary treatments: a control group (0% lemon grass) and four experimental groups supplemented with 0.25%, 0.50%, 0.75%, and 1.0% lemon grass. The experiment lasted for 56 days. Results indicated that dietary lemon grass supplementation significantly (P < 0.05) enhanced villus height and crypt depth in the duodenum and ileum, particularly at higher inclusion levels. However, no significant (P > 0.05) changes were observed in jejunal villi height across treatments. These findings suggest that lemon grass can positively influence intestinal morphology, potentially improving nutrient absorption and overall gut health in weaner rabbits. Further research is required to elucidate the specific mechanisms underlying these effects and to optimize the inclusion rate of lemon grass in rabbit diets.

Abstract<br> According to the National Scientific Council, a child's academic achievement is influenced by a variety of factors, one of which is their family background. The studies have shown that children from higher socioeconomic backgrounds tend to have better academic achievement compared to those from lower socioeconomic backgrounds. This can be attributed to factors such as access resources, parental involvement, and familial expectations. Additionally, parent occupation, family structure, and parental education level also play a significant role in a child's academic success. Understanding the impact of family background on student academic achievement can help educators and policymakers develop strategies to support and improve academic outcomes for all students, regardless of their family background.

ABSTRACT<br><br> The purpose of this study is to examine the effects of workforce diversity on employee performance. The survey research design method was adopted for the study. The instrument used to gather relevant data for the study was the questionnaire. The study centre on the Nigerian Banking Sector to examine the level of diversity practiced in terms of gender, age, ethnicity and educational in Nigerian Organizations. First Bank of Nigeria Plc, Gboko, Benue State was the focal organization. A total of 81 copies of questionnaire were disseminated to the respondents of the study and they were all filled and returned and also relevant for the study. In order to attain the research objectives, four hypotheses were created. The data were collated and analyzed using the Statistical Package for Social Sciences (SPSS) percentages and frequencies tables were used to for the descriptive aspects. To test the hypotheses, Spearman Rank Correlation Coefficient Analysis was adopted, Regression Model, Anova were adopted to examine the relationship between variables and identify the influence of the independent variables on the dependent variable. The limitation to the study is that the study made use of only few aspects of workforce diversity and as such, findings cannot be generalized to cover other dimensions of diversity not covered in the study. The research findings showed all aspects of workforce diversity used in the study has a significant relationship with employee performance except for ethnic diversity. It was also discovered that gender, age and educational diversity have strong influence on employee performance. Hence, based on findings, it is recommended that management continue to uphold its diversity policies and practices in order to increase the benefits of diversity. Management should ensure that all employees are properly trained on diversity issues as these trainings will also help employees to change those unconscious behaviours that hinder diversity and inclusion practices.<br><br> .

As students of materials and metallurgical engineering over the years we have been confused of how thermograms, and micrographs come about and how to possibly read the graphs and know the possible structures that will give the best mechanical properties. Although we have been studying this on literature but we determine to make this an experience by bringing to reality what we have only be seeing in test books and in lecture materials. Defferential scanning calorimeter was use to heat the hss tool to a desired temperature valure above the austenite temperature of 727°c and cooled rapidely in bline solution, cold water, and air and we study how each of this cooling media respond to mechanical properties of hss drill bit.The heat treatment of tool steel is one of the most important aspects of the final tool. Without proper heat treatment, the quality and functionality of the tool is degraded to the point where it becomes unusable. A correctly designed heat treating process ensures that the final product, functions according to design and intent, and also meet all desired performance specifications. The effect of the heating and quenching was carefuly studied, we could study the phases transformations, The effect of grain size in the hardness of the tool and the effect of each cooling medium on the tool steel.

ABSTRACT<br> This study examined Climate Change and Outbound Tourist Destination Choice of Port Harcourt<br> International Airport, River State, with a focus on environmental challenges such as air pollution,<br> flooding, temperature rise, and climate change awareness. A survey research design was adopted,<br> and data were collected from 214 distributed questionnaires, out of which 200 (93.46%) were fully<br> completed and analyzed. Descriptive statistics (mean and standard deviation) and regression<br> analysis were employed to test the hypotheses. Findings revealed that air pollution, particularly<br> black soot, significantly discourages tourists from visiting Port Harcourt, with a grand mean of<br> 3.51 (SD = 0.70). Respondents strongly agreed that poor air quality reduces the aesthetic appeal<br> of tourist sites and raises health concerns, although efforts to reduce air pollution (M = 3.72) would<br> encourage more visits. Flooding and extreme weather were also identified as major barriers,<br> recording a grand mean of 3.52 (SD = 0.68). Tourists agreed that flooded roads reduce accessibility<br> (M = 3.62) and that improved flood management (M = 3.65) would boost tourism. Similarly,<br> environmental concerns such as temperature rise and rainfall patterns had a negative effect on<br> tourism flow, with a grand mean of 3.48 (SD = 0.71). Avoidance of the rainy season (M = 3.60)<br> and reliance on weather forecasts (M = 3.55) were strongly emphasized. Tourists’ awareness of<br> climate change also influenced their travel behavior, with a grand mean of 3.49 (SD = 0.69). Many<br> agreed that climate change is a serious issue that should be considered in tourism planning (M =<br> 3.70) and that eco-friendly destinations were more attractive (M = 3.60). Regression results further<br> revealed that air pollution (β = 0.1977, p = 0.0228), flooding and extreme weather (β = 0.3203, p<br> < 0.001), and environmental concerns (β = 0.1393, p = 0.0386) significantly influenced tourists’<br> destination choices, explaining 33.85% (R² = 0.3385) of the variation

This study explores the performance of WiFi and Bluetooth networks by analyzing the Signal-to-Interference Ratio (SIR) in various locations within a building and a residential setting in Otuoke. Measurements were collected from multiple locations within a building for WiFi networks and from a residential setting for Bluetooth networks. The analysis focused on elements such as signal strength and interference strength to assess their impact on SIR. The results indicate that WiFi networks tend to have higher SIR values compared to Bluetooth networks, with aspects like access point positioning and interference management being crucial to WiFi's effectiveness. On the other hand, Bluetooth networks showed stable performance across different locations, emphasizing their reliability in short-range communication. The study provides practical recommendations for optimizing wireless network performance, including strategies for enhancing signal quality and managing wireless networks. It also suggests future research directions, such as exploring dynamic optimization techniques and integrating IoT systems to further advance wireless networking. While the study faced limitations, including a small sample size and environmental variability, it offers valuable insights into WiFi and Bluetooth performance, contributing to the development of better network optimization practices and improving user experiences.
